BEVERAGE EXTRACT.

Battle Creek, Michigan, have invented'a new and useful Improvement inBeverage Extracts, which invention is fully set forth in the. followingspecification.

This invention relates to beverage extracts and has for its object toprovide an extract of this class from rpasted carbohydrate materialscontaining edible leguminous beans such as peanuts, peas, and ordiwater,give a pleasant aroma and bitter flavor, will be nutritious and will notcon; tain any alkaloid or other injurious substances.

Table beverages have heretofore been prepared from roasted peas, beans,acorns, wheat and other cereals by steeping or per-. colating theroasted material and serving in a manner similar to serving coffee. lltis found by experience that the time required for the preparation ofsuch beverages is practically prohibitive of its use where quick serviceis demanded, as in hotels and restaurants. Furthermore, to secure thebest'result in making such beverages, care is required according to thenature of the preparation, in the matter of time, temperature, andproportions of water to the materials, whereby the beverage may be clearand'possess to the fullest extent the flavor and desirable propertiescharacteristic of the roasted product.

I overcome the above objections by making a quickly soluble solidextract of the roasted materials, and I prepare this-extract in a-mannersuch that the characteristics of flavor and aroma of the roastedmaterials are retained unchanged in the solid extract,

and all or so much of the extractive matter is taken out of thematerials as is desirable to secure the best results in thematters oftaste, flavor and character of nutritive material in the finishedproduct.

To facilitate solution of the solid extract,

T find it desirable to prepare it in a rather coarse granular form. Thiscondition in general better resists the hygroscopic tendencies of theproduct, although I may repare it in any degree of fineness desire Forthe purpose of illustrating the invention, ll have herein .recltedspecific ingreclients and proportions, but I do not desire to berestricted to this specific example be- Speclflcatlon of Letters Patent.Application filed Maym, 1912.

cause certain of the ingredients may be omitted and the roportions maybe varied wlthin wide limits without sacrificing all the advantages ofthe invention.

The starting materials which I propose to use for making the roastedproduct from which I prepare the soluble extract are edible le uminousbeans, such as peanuts, peas, or inary beans and bran with New Orleansmolasses. While I prefer to use a mixture of peanuts, peas and ordinarybeans, I may use any one or more of these leguminous products and whileI prefer molasses any saccharine body. such as sugar, syrup, cane orglucose and even sugar-containing fruits such as figs or other fruitsmay be used. The bran is preferably Wheat bran though other cereal bransmay be substituted.

Assuming the beverage extract is to be prepared from peanuts, peas,beans, wheat bran and New Orleans molasses, the bran is mixed with aboutof molasses and steamed in order to render the mass homogeneous, and isthen dried and roasted, the temperature being carried to the point ofbrowning to thoroughly caramelize the sugar of the molasses. A slightcarbonizing is not injurious and brings out desirable flavors. Thepeanuts, peas and beans are separately roasted to a dark brown color andground separately. I Ten parts of roasted bran and molasses are mixedwith one part each of roasted peanuts, peas and beans and treated withwater to produce the a ueous extract. This extraction may be e ected bytreating the roasted roduct with either cold or warm water or y boilingthesame therewith. I refer, however, percolation with Water at a out 50to 60 CI thereb obtainin usually a clear solution whic is ready forevaporation with or without undergoing a separate step of filtration.The clear aqueous solution is next concentrated by evaporation to asolid. This operation is preferably conducted in a vacuum pan on arotary drum in vacuo, the usual precautions well known to those skilledin this art being taken to prevent injurious heating of the product. Thedried extract is then comminuted or reduced to grains, powder, flakes orother subdivided orm and is ready for packing. The resulting product isa beverage extract of'extreme solubility in water, either hot or coldand when a teaspoonful of the extract is dissolved in a cup of hotwater, solution is effected in onc minute or less. The resultingbeverage is very palatable and possesses a pleasant aroma.

What I claim 18;

'1. A solid soluble extract for preparing beverages, consisting ofextractive matter in readily soluble form of roasted edible leguminousbeans, bran and caramelized saccharine material.

' 2. A solid soluble extract for preparing beverages, consisting ofextractive matter in readily soluble form of roasted peanuts,

peas, ordinary beans, bran and caramelized 15 saccharine material.
